A DNA fingerprint is a pattern of dark bands on photographic film that is made when DNA fragments are separated by gel electrophoresis and tagged.

Answer:

B) DNA fingerprint

Explanation:

DNA fingerprint is developed by a technique called DNA fingerprinting. It is a technique to identify an individual by examining their DNA. In the process, the DNA is isolated from the sample then the DNA fragments are then multiplied using a reaction called Polymerase Chain Reaction (PCR). The amplified DNA sample gets split into different visible bands by using gel electrophoresis. Banding pattern formed by an individual’s DNA is unique. The bands of two or more DNA samples can then be compared using the software.
